*COMPUTE EFFECTIVE STRAINS FROM STRAIN-TENSOR*
==============================================

Converts a full 6-component strain tensor (εX, εY, εZ, εXY, εYZ, εZX) into a single scalar curve representing either the von Mises effective strain or the mean (hydrostatic) strain. Use this worker whenever post-processing simulation or test strain-tensor histories requires a single representative scalar metric.

     - 
     - Ordered set of 6 strain-component curves (εX, εY, εZ, εXY, εYZ, εZX) as time- or load-step histories; multiple tensor sets can be supplied simultaneously for batch processing.
   * - Return Type

     - Scalar reduction mode: 'effective' computes the von Mises effective strain (default), 'mean' computes the hydrostatic (mean) strain; leave as default unless a volumetric/mean metric is specifically required.
